The invention discloses a high-performance intelligent bus duct for a data center, which includes a housing, mounting frames are provided on the inner walls of the left and right sides of the housing, and a transverse clamping connection is provided between the mounting frame and the housing There are several supporting frames, and there is a fixed frame between the two mounting frames. The fixed frame is composed of a main support rod, an auxiliary support rod, a fixed rod, a spring, and a spring fixing groove. The top and bottom of the stop block, the cavity formed after the installation frame and the support frame are clamped are equipped with conductive row card slots, and conductive copper bars are arranged in the conductive row card slots. The device is equipped with a fixed rod. There is a spring in the fixed rod, the function of the spring can resist and fix the shell, and the fixing effect is better. The installation frame and the support frame are clamped, which is convenient for adjustment and disassembly. The size adjusts the size of the cavity, and the conductive copper bar is clamped inside the bus duct shell to avoid the exposure of the conductive copper bar.
